Place your 6309/6309E/6809/6809E CPU into this adapter and then plug the adapter into the CPU socket. This then adds pull-up resistors to the R/W line and the entire address bus, enabling enhanced reliability for complex add-ons. See 6809 Pull-up Resistors.
This kit version is suitable for those with moderate to high experience in soldering. It contains one 1.27mm pitch surface mount device which will need soldering with care. Build instructions can be found here.
